even if my statement is not requested - here it is:

i still do go with the expression:

the universe is ever (i could do better in german)

as i also stated(my personal view): there are more or less minor changes in particular points in space but as a maximum has kind of instant effect (in terms of time) on a star (born or ready to die)

i personally cannot accept all so called astronomical observations that's the same with so called scientifc proof. i PERSONALLY just cannot accept everyhting.

i personally guess that once we are able to get some equipment directed to interstellar space - we'll get a complete different view about many things - sure-voyager is on its way already-but not able to communicate (?) and overall important not able making any meaningful measurements - maybe nasa (i wouldn't go with esa) is going to send some other probe at a faster pace into that direction which is capable of doing a great job out there. sure at a later stage we have to focus on the intergalactic space, ++++

Are there any scientific facts that you have accepted? For example, what goes up must come down (law of gravity). If I say, that there is a point in outer space where the gravity of earth-moon-sun system is exactly zero. However, this point is not stable due to perturbations from other planets. The healthy normal body temperature is 37 degrees Celsius or 98.6 degrees Fahrenheit and that the temperature of stars and even the vacuum can be measured. These are all scientific facts.

i agree somehow with the following scientific facts:

current human body temperature is about 98.6 degrees fahrenheit. (even if a more exact definition (temperature distribution) should be used and always linked to time)
currently echidnas maintain a range of body temperatures which usually lies between 77 and 98.6 degrees fahrenheit and have difficulty cooling down (source nasa - also not exact enough-same as above)

i don't agree with the following:

temperature, etc. of distant stars (or even our generous sun), stars in development(start/end/mass distribution/rays/...) cannot be measured exactly (not even close) until now by humans on earth or with probes - we still lack lots of knowledge about our "own" sun .... we'll be having hard time getting something close to it .... - sure research/engineering will provide new materials to get a bit closer ... bit after bit ... we're still kind of caged but free ...

Since Sir Arthur S. Eddington published his book entitled: ‘The Internal Constitution of the Stars’ in 1926 much have been learned about the making of the Sun. Three other principal contributors to our knowledge about the Sun were Subrahmanyan Chandrasekhar, William A. Fowler, and Hans A. Bethe. Although Eddington was the one who started it all, the irony is that he never received a Nobel Prize for his achievements. As physicists, as Bohr and Einstein, Eddington and Chandrasekhar did share many things; for some unknown reasons, they were constantly fighting and arguing with each other about some theoretical concepts, they could not seem to agree on some unclear fundamental principles.

The facts are: the age of the sun estimated as 4 600 000 000 years. Its diameter is 1 392 000 kilometers. Its mass is 2 000 000 000 000 000 000 000 000 000 000 kilograms (about 330 000 times of Earth’s mass). Its density is about 1.4 times of water. Core temperature is about 15 000 000 kelvins. Corona’s temperature lies between 5000 and 2 millions kelvins. The energy output by fusion process is 5 000 000 000 kilograms per second. At this rate, the Sun will burn out completely in 12 000 000 000 000 years. The Sun rotates at different rates at the pole 36 days and 25 days at the equator. The energetic gamma photons generated at the core take 100 000 years to reach the surface of the Sun. Therefore, it seems that light moves at the speed of 12 centimeters per hour inside the interior of the Sun. The solar activities follow roughly an 11.3 years cycle between minimum and maximum of the sunspots counted on the visible surface. However, overall numbers of sunspots follow an upward trend, which are more and more sunspots during peak years as the Sun ages. Nevertheless, its place in the universe, the Sun is an average single star in an average galaxy dominated by binary stars systems.

Note: The facts given above could not possibly or drastically affected or effected by the mystery of the missing solar neutrinos. The data were partly compiled using spectral analyses.

or maybe human race should rather stop messing around with our generous sun ....

don't simulate - rather exploit while you can ...

that meaning solar cells, fuel cells, and sure research will come up with something new every now and then ... BUT ...

we don't know what black holes are all about ...

[AntonioLao]

For anyone curious about black hole, the following book remains Chandrasekhar's legacy on this particular subject matter

The Mathematical Theory of Black Holes (Oxford Classic Texts in the Physical Sciences)

[undef00]

you may come up with an answer what black holes are all about by yourself - sure!!!

[AntonioLao]

I think black holes are where all kind of time axes are forced to align together relatively to the universal axis of time. And the mother of all time axes is the big bang singularity where absolutely all time axes (infinite of them) are aligned with the universal time axis.

The current temperature is about 3 Kelvin. Where are we going from there? We could heat up or cool down some more, but to stay at 2.7 is unlikely, isn't it? Nobody really says much. They certainly aren't making big plans.

3 kelvins would be the same as the temperature of outer space. This is the same temperature that an astronaut exposed to on the side not facing the sun when doing a space walk.
